typical example of a two-variable two linear equations, system

x price of shirt
y price of hat
system%284x%2B6y=62%2C4x%2B2y=34%29
and this description allows easy elimination of the x to quickly find y.

    If you read the condition ATTENTIVELY, you IMMEDIATELY will see that

    the difference in their buyings is  6 - 2 = 4 hats, and the difference in their spendings is 62 - 34 = 28.


    Hence, one hat price is  28/4 = 7 dollars.


    From this point, YOU do the rest ON YOUR OWN.
